You have a large bag and a set of numbered coins from 1 to n. You start by added coins with the numbers 1,2,3,4,5 into the bag. Then you take out the coin with the number 1 and set it aside. Now there should be 4 coins in the bag. You then add the numbers 6,7,8,9,10 into the bag and remove the 2 coin. There should be 8 coins in the bag. If you could repeat this procedure an infinite number of times, how many coins will be in the bag?
